Ancient Coin Puzzle | 14 Oct 2009

Thief once got hold of coin which read 250 B.C. so he understood it is an ancient coin and wanted a great price for it and one day he read something that lit his eyes. He saw "We buy BC coins at the rate of 100 $ per year old starting at $10,000 for the first year".

Since the current year is 2009AD and the coin dates back to 250BC.
So the difference in yrs is 2009-(-250) = 2259
And the prize is only for old coins so current year would not yield any money
2259-1=2258
and $100/year and $10,000 for first year so... 2257*100+10000 = 235700
